C177600100012 SAMPLE A 9.5-cm diameter rotating target wheel containing C177600100013 four target segments with 440, 340, 320, and 270 C177600100014 mu-g/cm2 of 242Pu in form PuO2 as PuO2 on 2.4 mu-m C177600100015 thick Ti backing. Pu target was enriched in 242Pu C177600100016 more than 99.9%.The targets were prepared by C177600100017 molecular plating. 48Ca beam entered BGS through a C177600100018 45 mu-g/cm2 thick carbon window. C177600100019 DETECTOR (MWPC,SISD) Focal plane detector consisted of C177600100020 multiwire proportional counter, used to determine C177600100021 time of flight and location of impact of evaporation C177600100022 residues. Second focal plane detector consists of C177600100023 48 Si-strips (three 6x6cm2 cards, sixteen strips each),C177600100024 which provide horizontal resolution and was used for C177600100025 implantation of evaporation residues. Vertical positionC177600100026 was determined by resistive charge division within C177600100027 each strip. C177600100028 METHOD (OLMS,TOF) C177600100029 INC-SOURCE 48Ca11+ beam produced by Advanced Electron Cyclotron C177600100030 Resonance source was accelerated to 263 MeV by the C177600100031 LBNL 88-Inch Cyclotron with typical intensities of C177600100032 300 - 400 pnA.
